There is a lot going on about the safety of the A380 and the reason for the failure of the engine on the Qantas A380 is still unknown but whats shocking is that the blades went through the wings and so the passengers and crew were lucky. Some airlines aren’t grounding their planes like Emirates and Singapore, but Qantas grounded their planes until this investigation is completed. They have a problem with the Rolls Royce Trent 900 engine, they still don’t know the main reason for the failure, the second is that parts fly out the back end and punctured the wings. Usually the front end of the engine can contain the blades if something goes wrong, but it seems part flew out the back end which didn’t contain the parts and damaged the wings, in principle if an engine is damaged its supposed to be designed in a way to contain the damage and not damage the rest of the plane.
When purchasing the A380s from Airbus you get two choices of engines, either a Rolls Royce Trent 900 or a GE and Pratt & Whitney GP7200. There are three airplane engine manufacturers in the world; GE, Pratt & Whitney, and Rolls Royce. Pratt & Whitney and GE decided on a joint venture to develop the engine for the Airbus 380. So in this case the GP7200 has no issues and all the A380s ordered by Emirates have the GE and Pratt & Whitney GP7200 so there is no reason to ground those planes. So the A380s from Emirates are safe to fly but I heard business class service in the planes isn’t too good and its understaffed, too many passengers and too few crew.
